To adjust the accelerator pump on a Weber carburetor, first locate the adjustment screw on the pump mechanism. Turn the screw clockwise to increase the pump's output or counterclockwise to decrease it. After making adjustments, ensure the throttle is fully closed and check for a proper squirt of fuel when the throttle is opened quickly. Fine-tune as necessary to achieve optimal performance without flooding the engine.
